PTC Headwinds on Railroad Operations
Phase 2 Reliability Study being
Launched by AAR, adds:
Actual hardware performance
Software performance
Human Factors
Conservative predictive braking
Ability to analyze trade offs between repair capability and train delay (Broke/Fix and Preemptive Replacement)
TCCO’s New Mission & Focus 5/2015
Improve safety and deliver solutions that recover
lost capacity (and improve lifecycle costs)
introduced by PTC.
Capacity headwind must become a tailwind.
• Capacity gains don’t necessarily have to
come via the PTC system.
Solutions must show favorable ROI vs other
capacity investment options.

New Schedule for TCCO Committee
Meetings and Conference Calls
Historically, one meeting per year to review progress and to
introduce and rank new project concepts
New process has regular conference calls in addition to
face-to-face meetings as needed
Regular high-level status/review of ongoing projects
Review and refinement by the committee of project concepts
as they are developed into project frameworks
Rank new project concepts throughout the year, to provide
better direction for application of funding
Monthly project review with FRA
Established TCCO Executive Committee
Detailed development of strategies, project concepts and
frameworks for review/approval by full committee
FRA Involvement with TCCO Committee
Engaged FRA more regularly than in past years
Regular calls and meetings with FRA and TCCO executive committee.
Project concept and framework development with focus on key FRA metrics
1. Project alignment with DOT/FRA goals (safety, state of good repair, efficiency, competitiveness, environment impact)
2. Safety impact on RR operations
3. Technology maturity, what TRL level? New technology or ready to deploy?
4. Industry need, how much demand is there from the railroad industry?
5. Partnership and cost sharing
6. NTSB recommendation
7. Short term or long term impact on rail operations
8. Other dynamic requests from the FRA
Expansion of TCCO Participation
Objectives
To ensure project concepts offer benefits to the broad industry
• Also to increase the probability of receiving FRA funding.
To incorporate feedback from smaller railroads, commuters, etc.,
in development of project concepts and throughout the project
lifecycle
Approach
1. Expanded participation to additional AAR member railroads
2. Expanded participation to non AAR member railroads –
Expand TCCO Executive Committee as was done for our AAR
PTC Interchange Agreement (non members)
1. We formally invited commuters, shortlines and terminal
railroads to cooperate with TCCO at a PTC meeting held at
Metra/Chicago in 2015.
